Patented Apr. 5, 1932 UNITED STATES PATENT orrlcs ALFRED W. KATI-I ANDBURTON W. SCOTT, OF DETROIT, MICHIGAN, ASSIGNORS TO ARTHUR COLTONCOMPANY, 013 DETROIT, MICHIGAN, A CORPORATION OF MICH- IGAN MACHINE FORSTAGKING LOZENGES Original application filed January 11, 1926, SerialNo. 80,449. Divided and this application filed February 25, 1929.

This invention consists of novel cooperating means for arranging apredetermined number of circular discs or lozenges of metal,confectionary or other materials into a cylinder or stack andtransferring the stack to a wrapping belt, where it may be wrapped.

It also consists of the details of construction illustrated in theaccompanying drawings and particularly pointed out in the claims.

In the accompanying drawings, Fig. 1 is a plan of this improved machinewith a portion of the assembling and carrying devices omitted. Fig. 2 isa side elevation of the machine. Fig. 3 is a plan of the drivingmechanism beneath the table which is broken away. Fig. 4 is a section onthe line 44 of Fig. 1, on a larger scale. Fig. 5 is a partiallongitudinal elevation showing a portion of the wrapping belt. Fig. 6 isa plan and Fig. 7 is a side elevation of the assembling mechanism. Fig.8 is a section on the line 8-8 of Fig. 6.

Similar reference characters refer to like parts throughout the severalviews.

The claimed parts of the present machine include a rack or receiver forthe discs to be wrapped embodying a series of converging troughs; astack forming means and a transfer deviceor carrier which engages thetwo end discs of the stack to be wrapped'and, pressing the discstogether, conveys the stack to a wrapping belt; and mechanism to causethe several devices to operate harmoniously and in order.

All of this mechanism is mounted on the top and on the lower side of thetable 1 which may be supported on legs 2, and is shown to be driven by across shaft 3 (Fig.

Any desired means may be employed to drive this shaft, an electric motor4 being shown provided with a pulley 5 from which a belt 5a runs to thetight and loose pulleys 6 and 7 on the cross shaft, a shifter 8 for thebelt being supplied. This cross shaft is provided with a worm (notshown) which meshes with a worm wheel 9 on the main shaft 10. A pulley12 for the round belt 13 is also mounted on this cross shaft. A handwheel 14 may be employedto turn the cross shaft but this is Serial No.342,390.

preferably normally disengaged by sliding.

it along the shaft to relieve the machine of the inertia of this wheel.The main shaft 10 makes one rotation for each operation of the machine.Stack forming The receiver for the discs to be wrapped is shown in Figs.1, 2, 6, 7 and 8 and consists of an inclined plate 16 supported bybrackets 17 and 18 and having a series of ribs or partitions 19 on itsupper surface, which ribs may be parallel at their upper ends butconverge lower down. The discs A are dumped onto the upper end of thereceiver and are caused to assume vertical positions in the spacesbetween these ribs by means of the rotating brushes 20 on the shaft 21mounted in bearings 22 that are carried by the receiver, the pulley 23on this shaft being driven by a belt 30 running to the pulley 31 on asmall countershaft 32 (Fig. 2) and a second pulley 33 on thiscountershaft receives the belt 13.

The discs fill the troughs between the ribs 19 and roll down untilstopped by the spring held fingers 24 carried by the cross bar 25mounted on the arms 26. These arms are pivoted on the shaft 27 mountedin the brackets 28 at the lower end of the receiver and are swung up anddown by the link 29 (Fig. 7.) Fig. 5 shows how this link connects to asmall lever 36, pivoted at 37 to a bracket 38 (Fig. 3) which extendsdown from a platform 35 on the table 1. This lever carries a roller 39which runs on the cam 40 mounted on the shaft 41 carried in bearings 42and 43, formed on the brackets 38 and 44. This shaft connects to theshaft 45 by means of the similar gears 46 and 47 and the latter shaft isdriven from the main shaft 10 by means of similar gears 48 and 49. Ateach rotation of the main shaft therefore, the bar 25 rises and permitsa row of discs to run down until they are stopped by the swinging stopbar 50 which is carried by arms 52 mounted on the shaft 53 carried bythe brackets 28. This stop bar is normally held in position by a spring54 against the stops 55. When against the stop bar the discs aresupported by an apron 56 pivoted at 57 (Fig. 7), and held up by thespring 58. A stop 59, also on the bracket 28, limits the downwardmovement of the arm 26, cross bar 25 and of the fingers 24.

Stack transfer The carrier to transfer the stack of discs from above theapron 56 to the wrapping belt is shown in Figs. 1, 2, 3, 4 and 5. Acrank disc 60 on the end of the shaft 45 (Fig. 3) carries a crank pin 61which extends through the lower end of the connecting rod 62, and theshaft 45 makes one turn for each cycle of the machine. The connectingrod 62 is attached to the pin 63 at the end of the crank arm 64 attachedto the hub 65 which is rotatable on the shaft 66 carried by a pedestal67. A brake drum 68 on one end of this shaft, engaged by a band 69mounted on the pin 70 carried by the pedestal 67, restrains but does notprevent absolutely the rotation of this shaft. The friction iscontrolled by a bolt 72, spring 73 and nut 74 shown in Fig. 5.

Slidable on but keyed to the shaft- 66 are the hubs 74 to which the arms75 connect. Cam plates 76 are attached to the inner sides of these armsand end in lugs 77 and 78. A cross bar 79 slidable in and rotatable withthe hub 65 has rounded ends engaging the cam plates 76 which arenormally drawn toward each other by the spring shown in Fig. 1.

When the rod 62 moves down the cross bar 79 will move up, the brakerestraining the shaft 66 from turning. Thus the cross bar 79 and the camplates 76 will cause the arms 75 to separate along the shaft 66, whenthe cross bar reaches and abuts the lugs 77, the arms 75 will be swungup, while separated, until they reach the position shown in Fig. 8. Thecross bar 79 then slides down the cam plates 76 and the arms 75 cometogether due to the spring 80, so as to grip a stack of discs. When thecross bar reaches the lugs 78 the arms 75 holding a stack of discsbetween them, will swing down to the position shown in Fig. 2, placingthe stack of discs on the wrapping belt 84.

The brake on shaft 66 prevents rotation thereof when hub 65 is rotatedbut permits shaft 66 to rotate when hubs 74 are caused to rotate by thecross bar 79.

The arms, therefore, rest at the upper and lower ends of their movementswhile the cross bar 79 slides along the cam plates 76. The arms separatewhile at their lower position to release the stack of discs. They areseparated sufliciently to pass the ends of the apron 56 and of the crossbar 50 when they move up, but when they come down, they simply swingthese two supports out of the way, the arms 52 carrying the cross bar 50being swung out, as shown in Fig. 2, and

the apron being swung down on its pivot 57 in a manner which will beobvious.
